Before you start

Log in to the Tridify BIM Publishing Service and upload and process your IFC file. Import the Tridify BIM Tools into your Unity project. If you have previously imported the Tools into Unity, make sure you have the latest version.

1. Log in to your Tridify Account

In Unity go to Tools › Tridify › Conversion Projects.

 

BIM_Tools_import_model_1


In the Conversions window, log in using the same email and password you used when you logged in to the Tridify BIM Publishing Service in your browser.

The list of your Projects will appear.

When the processed file opens, you will see the folders created based on your IFC file. If you expand the folders, you will notice that objects are further grouped by type; all walls, doors, furniture, etc. are organised according to their IFC Type.

Select the floors or IFC Types you want to import. For really large models, it is recommended to bring one floor at a time. If you don't need the IFC Type IfcSpace, you can deselect the spaces at this point. You can also hide them later in the Inspector window.

Extra info

You can find the associated IFC data in the Inspector window by selecting an object in your model.

We recommend you to create a Prefab Asset of the imported model. When a building is imported into Unity using the Tridify BIM Tools, the IFC data is attached only to the objects that are in the Hierarchy window. In the Project window you'll find models and their meshes but they won’t have IFC data attached. When you create a Prefab you'll retain the building model and its IFC data in your project for later use.
